Epithelial ingrowth is a rare condition that is generally seen after laser keratomileusis (LASIK) and has been reported in the literature in a small number of cases after small-incision lenticule extraction (SMILE) surgery. "Epithelial inoculation" should also be considered in patients presenting with decreased vision and an appearance similar to epithelial ingrowth in the early period after SMILE surgery. A 23-year-old woman presented to our clinic with a request for refractive surgery.

Purpose: The aim of this study was to investigate the effect of the keratoconus (KC) stage according to the Amsler-Krumeich classification system and the parameters used in this classification on deep anterior lamellar keratoplasty outcomes.

Methods: The preoperative KC stage was determined, and the presence of corneal scarring was noted. The preoperative and postoperative best-corrected visual acuity (BCVA), refractive error, mean central keratometry (K mean ) readings, topographic astigmatism, and minimum corneal thickness (CT) values were recorded.

Purpose: The aim of the study is to compare the accelerated epithelial-on corneal collagen cross-linking (epi-on CXL) and accelerated epithelial-off corneal collagen cross-linking (epi-off CXL) in terms of clinical and confocal microscopy results.

Materials And Methods: Forty-two eyes of 21 patients with progressive keratoconus and simultaneously undergoing accelerated epi-on CXL in one eye and accelerated epi-off CXL in other eye were evaluated. Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA) with spectacle in logMAR and topographic findings (mean keratometry [ ] and maximum keratometry [) were recorded at 1, 3, 6, 12, 18, 24, and 30 months.

To the best of our knowledge, this is the second reported case of keratitis (AK) as a result of scleral lens use and the first case of AK associated with Maxim scleral lens use (Accu-Lens, Inc., Lakewood, CO, USA). A 22-year-old male scleral lens user presented at the department of ophthalmology at Gazi University Hospital complaining of painful corneal opacities and erosion in the cornea of right eye.

To present a case with progressive keratoconus after treated with radial keratotomy (RK) and was undergone corneal collagen cross-linking (CXL) for preventing the progress of keratectasia. A progressive keratoconus case who was previously treated with RK was undergone corneal collagen cross-linking (CXL) in her left eye for preventing the progress of keratectasia. After the CXL procedure performed at another clinic, best-corrected visual acuity (BCVA) of her left eye decreased from 0.

Purpose: To evaluate the effects of air bubbles on clear corneal incision (CCI) in patients who had phacoemulsification surgery, and to compare this type of CCI architecture with patients who had no air bubbles after phacoemulsification surgery, using anterior segment optical coherence tomography (AS-OCT).

Methods: Eyes which had undergone uneventful phacoemulsification cataract surgery with implantation of a posterior chamber intraocular lens (IOL) were equally randomized into two groups. Group 1 comprised patients with anterior chamber air bubble injection after phacoemulsification, and Group 2 comprised patients who had undergone phacoemulsification surgery without anterior chamber air bubble.
